Problems solved by technology

However, the multimedia interfaces in the prior art need to be connected by cables, and most multimedia interfaces have certain requirements on the length of the cables, such as the cable length of the DVI (Digital Visual Interface, Digital Video Interface) interface needs to be less than 8 meters, otherwise the signal transmission quality will degrade
In this way, users will be bound by cables when using multimedia devices, and cannot place or move the connected devices at will.

Abstract

The invention discloses a wireless conversion device of a multimedia interface. The wireless conversion device comprises a first signal conversion processing module, a repeater circuit, and a wireless communication module. There is circuit connection between the repeater circuit and the wireless communication module and the first signal conversion processing module. According to the provided wireless conversion device of a multimedia interface in the invention, it can be realized that a multi-media signal is converted into a wireless signal to carry out transmission only by realizing circuit connection with electronic equipment; a user can user the conversion device to connect wirelessly the electronic equipment and sharing of multimedia signals will not be constrained by a cable; besides, the used electronic equipment can be placed or moved at will.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to an interface conversion device. Background technique [0002] With the development of network and multimedia technology, multimedia access has been used more and more widely. Some common electronic devices, such as televisions, mobile phones, and multimedia players (MP4), are equipped with multimedia interfaces. However, the multimedia interfaces in the prior art need to be connected by cables, and most multimedia interfaces have certain requirements on the length of the cables, such as the cable length of the DVI (Digital Visual Interface, Digital Video Interface) interface needs to be less than 8 Otherwise, the quality of signal transmission will be degraded. In this way, users will be bound by cables when using multimedia devices, and cannot place or move the connected devices at will. Contents of the invention [0003] The object of the present invention is to p...
